At present, individual pigs on some pig farms are infected by a mixed infection of two or more pathogens, including bacteria, viruses, toxoplasmosis, and Eperythrozoon. After the affected pigs fall ill, treatment with antibiotics alone often gives poor results. Farmers report that penicillin fails to bring the fever down. In this situation, we should consider that the pig may be infected by more than two pathogens, which belongs to the category of complex and intractable swine diseases. The main signs of sick pigs are: (1) persistent high fever, reduced appetite, listlessness, constipation or diarrhea; (2) clear nasal discharge or mucus, with difficulty breathing

The main signs of sick pigs are:

(1) persistent high fever, reduced appetite, listlessness, constipation or diarrhea;

(2) clear nasal discharge or mucus, with difficulty breathing, rapid breathing, panting, and coughing;

(3) pestilent toxin and damp-heat, high fever, cessation of eating, dry and bound stool, scanty dark yellow urine, red and swollen conjunctiva, and red macular or papular skin lesions;
